Company mission
Refurbed's mission is to change the world for the better by making refurbished products the new normal.
Role
Who you are
- 10+ years of professional software engineering experience, including 4+ years in React Native / Expo
- Deep expertise in TypeScript, React Native, and modern mobile architecture patterns (navigation, modularization, OTA updates)
- Proven experience owning and evolving app architecture, influencing across teams, and driving adoption of standards
- Proficiency in native iOS (Swift) and/or Android (Kotlin) bridging and advanced SDK integration
- Track record of driving mobile performance initiatives (e.g., cold start optimization, crash-free stability >99.7%)
- Strong understanding of mobile CI/CD, release management, observability, and scaling across markets
- Clear communicator who can align stakeholders and influence technical direction without relying on hierarchy
- Strong judgment in leveraging AI tools (ChatGPT, CursorAI, etc.) — knowing when they accelerate delivery, when to avoid them, and how to uphold quality while using them
What the job involves
- This is a Staff-level Individual Contributor role (no people management). You’ll lead through architecture and delivery — and you’ll stay hands-on by shipping production code, reviewing critical changes, and unblocking releases
- Own and evolve the technical architecture of refurbed’s mobile app built with React Native / Expo
- Define and drive the modernization roadmap (navigation, modularization, OTA updates, build & release workflows)
- Design and implement cross-cutting systems for performance, scalability, and reliability
- Lead mobile performance and stability initiatives (e.g., cold start optimization, crash-free stability targets)
- Guide the integration of AI-powered experiences (chat-based shopping, voice, image search) into the app
- Own SDK and native integration strategies (e.g., Bloomreach, payments, analytics, experimentation)
- Establish best practices, patterns, and libraries used across multiple squads (platform mindset)
- Mentor engineers across teams through reviews, pairing, workshops, and pragmatic standards
- Collaborate closely with platform and backend engineers to ensure seamless end-to-end performance
- Represent the mobile domain in company-wide architecture reviews and technical roadmap discussions
Our take
Buying refurbished electronics can be a fantastic way to give a device a second life whilst saving a bit of cash, but many people are skeptical of doing so. Such items are often sold through illegitimate channels and there is no guarantee that the device will work for long, resulting in people avoiding refurbished goods.
Refurbed provides a refurbished electronics marketplace, which is challenging this. It allows users to browse and purchase refurbished devices that come with a minimum of 12 months' warranty.
The platform operates based on a monthly subscription fee, and whilst this will present a challenge when alternative marketplaces are free to use, the company has recognised that consumers are happy to pay for quality and warranty. Through its marketplace, the company aims to increase the prevalence of refurbished device purchases, helping to reduce waste and carbon footprints and helping consumers save money in the process. $40 million in 2025 funding is being invested into AI-driven efficiency and CX solutions.
